Techniques for Stenting the Normal and Obstructed Ureter

Ureteral obstruction is a common cause of urologic morbidity requiring quick and effective treatment, as prolonged obstruction can cause pain, infection, and eventual loss of renal function. Few would argue that initial drainage or bypassing of the obstruction is favorable initial management; however, urologists are oftentimes faced with technically difficult cases not responsive to the standard operative maneuvers. Recognizing the diversity of pathology and the potentially complicating issues, urologists should have in their armamentarium a systematic approach or algorithm for dealing with these common dilemmas, as well as an understanding of various tricks of the trade. This knowledge will prevent heightened anxiety at the time of surgery and will ensure the availability of the proper operative equipment. This article outlines an approach and discusses the obstacles and options in stenting the obstructed ureter.
